Stable Fit System 
      General trail running packs are designed based on male models, resulting in an inadequate fit for females. Female runners experience excessive shaking and discomfort while running, which negatively impacts their movements and overall performance.
      Research has revealed that during high-intensity running, women's breasts can experience displacement ranging from 4 to 10 cm.Calculating based on an average stride length of 60 cm, this means that over a distance of 30 kilometers, the movement trajectory of women's breasts can reach up to 2000 meters. Once ligament damage occurs, leading to breast sagging or looseness, it becomes challenging to restore the previous curvature of the breasts.
